Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{total}{count}[/tex]
given mean height of 12 men is 1.70 m , then
[tex]\frac{total}{12}[/tex] = 1.7 ( multiply both sides by 12 to clear the fraction )
total height = 12 × 1.7 = 20.4 m

Use the definition of exponents as repeated multiplication to simplify. Enter only the simplified expression (2/3)^2
The expression (2/3)² when simplified by repeated multiplication is 4/9
How to evaluate the expression?From the question. the expression is given as
(2/3)²
We start by rewriting the expression using repeated multiplication
This in other words means that:
We rewrite the (2/3)² as repeated multiplication
To do this, we apply the exponent rule of indices
This rule states that:
a^m = a * a * a .... in m places
So, we have
(2/3)² = (2/3) x (2/3)
Evaluate the products
(2/3)² = 4/9
Hence, the equivalent expression is 4/9

The ellipse given by x^2+xy+2y^2=7. The y-coordinate(s) of all points are -11.3, 11.2, -5.665, 5.585 where the ellipse has a vertical tangent line.
Define differentiation.Differentiation is the process of determining a function's derivative. Differentiating algebraic functions, trigonometric functions, and exponential functions are the three fundamental derivatives.
Given,
Ellipse given,
x²+ xy + y ² = 7
Differentiating:
dy/dx
x²+ xy + y² = 7
d/dx(x² + xy + y²) = d/dx(7)
2x + 1y + x dy/dx + 2y dy/dx = 0
dy/dx = 2x + y/ x + 2y
dy/dx = 0
2x + y = 0
x + 2y = 0
Now, we have 2 equations,
x² + xy + y² = 0
y = -2x
Solving equations by substitution method,
x² + x(-2x) + (-2x)² = 7
x² - 2x² + 4x² = 7
3x² = 7
x = ±√21/3
Using y = -2x
Points are:
( -2√21/3 , √21/3) and (2√21/3 , -√21/3)
±√21/3 = ±1.528
x² + xy + y² = 7 [-11.3, 11.2, -5.665, 5.585]}

The value of x in the second ordered pair is - 0.5 or - 1/2 and that of y in the first ordered pair is 8.
The given ordered pair is (-3,y) and (x,2)
the equation y=-2x+2
In the first step we put the value of x as -3 as given in (-3,y) in the equation y=-2x+2, we get
y=-2(-3)+2
⇒y=6+2
⇒y=8
So the value of y is 8 then the ordered pair will be (-3,8).
Again, in the second step, we put the value of y as 2 as given in (x,2) in the equation y=-2x+2, and we get
2=-2x+2
⇒2x=2-2
⇒2x=0
⇒x=0
So the value of x is 0, and the ordered pair will be (0,2).

a. George will win
b. jullia will win
The probability that George will win is 1/10 and the probability that Julia will win is 1/20.
What is probability?Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true.The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.The probability is calculated by dividing the total number of outcomes by the total number of potential events.So, calculate the probability as follows:
Probability formula: P(E) = Favourable events/Total eventsWe know,
The total number of tickets sold is 100.George has 10 tickets and Julia has 5.(A) George's probability of winning:
P(E) = Favourable events/Total eventsP(E) = 10/100P(E) = 1/10(B) Julia's probability of winning:
P(E) = Favourable events/Total eventsP(E) = 5/100P(E) = 1/20Therefore, the probability that George will win is 1/10 and the probability that Julia will win is 1/20.

Which ordered pair is a solution of the equation? 2 x + 4 y = 6 x − y 2x+4y=6x−y
The solution to the equation given as 2x + 4y = 6x − y has the ordered pair of (3, 4)
How to determine the ordered pair of the solution?From the question, we have the following equation that can be used in our computation:
2x+4y=6x−y
Solving further, we need to collect the like terms
So, the equation becomes
2x - 6x = -4y - y
Next, we evaluate the like terms in the above equation
So, we have the following representation
-4x = -3y
Divide both sides by -3
The equation becomes
x = 3/4y
At this point, we assume any value for y and then solve for x
Assume that the value of y is 4
So, we have the following representation
x = 3/4 * 4
Evaluate the products
x = 3
So, we have
x = 3 and y = 4
Express as ordered pairs
(x, y) = (3, 4)

How to Complete a table Using Equation?To complete a table of values, we can plug in the known value of each of the ordered pairs that are represented in a table into the given equation that models the relationship, then find the value of the missing variable.
The equation that represents the relationship between x and y is given as y = -3x - 1.
Find the value y in the ordered pair (-3, y) by substituting x = -3 into y = -3x - 1:
y = -3(-3) - 1 = 8
y = 8
Find the value x in the ordered pair (x, 2) by substituting y = 2 into y = -3x - 1:
2 = -3x - 1
Add 1 to both sides
3 = -3x
Divide both sides by -3
x = 3/-3
x = -1

A home developer is planning to build h houses with identical floor plans. Each house will have 3 smaller bedrooms that each require 150 square feet of carpet and 1 larger bedroom that requires 270 square feet of carpet.
The required expression is 3h(150) + h(270) which is the correct answer would be an option (D).
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
Since each house will have 3 smaller bedrooms that required 150 square feet of carpet
⇒ 3 × 150
Each house will have 1 larger bedroom that requires 270 square feet of carpet.
⇒ 270
So, (3 × 150 + 270) × h
⇒ 3h(150) + h(270)
Thus, The required expression is 3h(150) + h(270).
Hence, the correct answer would be an option (D).

The equation of the line perpendicular to the given line is, y = 3x + 1.
What is slope of the line?
The change in y coordinate relative to the change in x coordinate is referred to as a line's slope in mathematics. The symbols Δy and Δx stand for the net change in the y-coordinate and the net change in the x-coordinate, respectively. where "m" denotes a line's gradient. tanθ then represents the slope of a line.
Consider, the given equation of line
[tex]y = -\frac{1}{3}x+4[/tex]
We have to find the equation of line passes through the point (-2, -5) and perpendicular to the given line.
Here, the point is (-2, 5).
First to find the slope of the line.
Since, the slope of the line, perpendicular to the given line is negative reciprocal of the slope of given line.
Here, the slope of given line is, -1/3.
So, the slope of perpendicular line is [tex]-(\frac{1}{(-\frac{1}{3}) }) = 3[/tex]
Therefore, the slope of the line is 3.
Now to find the equation of the line.
Consider, the point - slope form of the line
[tex]y-y_1=m(x-x_1)[/tex]
Plug [tex](x_1, y_1) = (-2, -5) , m = 3[/tex]
⇒
[tex]y-(-5)=3(x-(-2))\\y+5=3(x+2)\\y+5=3x+6\\y=3x+6-5\\y=3x+1[/tex]

The perimeter of a triangle is 42 feet. One side of the triangle is one foot longer than the second side. The third side is five feet longer than the second side. Find the lengths of all three sides (in feet). (Enter your answers as a comma-separated list.)
Answer:
12 ft, 13 ft , 17 ft
Step-by-step explanation:
let x be the length of the second side , then
one side is x + 1
third side is x + 5
the perimeter P is the sum of the 3 sides, then
P = x + x + 1 + x + 5 ← collect like terms
P = 3x + 6
given P = 42 , then equating gives
3x + 6 = 42 ( subtract 6 from both sides )
3x = 36 ( divide both sides by 3 )
x = 12
x + 1 = 12 + 1 = 13
x + 5 = 12 + 5 = 17
the 3 sides are 12 ft, 13 ft , 17 ft
